[Role of acute alcohol poisoning and craniocerebral trauma in the mechanism of death caused by subarachnoid hemorrhage].

Objective: To investigate the relation between the expression of tPA, MMP-2, MMP-9 and AEG-1 in the human brain tissue and the ethanol concentration under the acute alcohol poison, and to analyze the role of alcohol and trauma in the mechanism of death of subarachnoid hemorrhage.

Methods: Fifteen real cases were collected in this study. The brain tissues were researched by histological examination and the concentration of ethanol in heart blood were detected.

[The role of diaphgram fatigue in the death from hanging with bound upper limbs of rabbits].

Objective: To explore the role of diaphgram fatigue in the death from hanging with bound upper limbs of rabbits.

Methods: Rabbits were hanged with upper limbs bound, then the data of EMGdi were gathered

Results: By analyzing power spectral of EMGdi in experiment, we compare the ratio change of H/L between pre-experiment and post-experiment. There is a significance decrease of the ratio of H/L, so it indicates that diaphgram fatigue does exist.
